Meta: Add license header to source files As suggested by Joshua, this commit adds the 2-clause BSD license as a comment block to the top of every source file. For the first pass, I've just added myself for simplicity. I encourage everyone to add themselves as copyright holders of any file they've added or modified in some significant way. If I've added myself in error somewhere, feel free to replace it with the appropriate copyright holder instead. Going forward, all new source files should include a license header.

SoundPlayer: Start working on a GUI sound player application This can play anything that AWavLoader can load (so obviously only WAV files at the moment.) It works by having a timer that wakes up every 100ms and tries to send a sample buffer to the AudioServer. If our server-side queue is full then we wait until the next timer iteration and try again. We display the most recently enqueued sample buffer in a nice little widget that just plots the samples in green-on-black. :^)
